How to import Adobe Launch Extension version into lib/actions JS file?

[ugobey]

In the code which will exist in runtime on the site, how do I get the version of the extension so we can send it with requests we will do from the client side browser?

Is there perhaps a way to get it from the Adobe Extension UI first?

By extension version I mean the version in the extension.json file of the package

Thanks

Unfortunately, no. Unless the developer has purposely made the version available, e.g. through a data element that the extension provides, you simply can't get the version number of an extension anywhere.

As a workaround, you can track the Environment Build Date and Time to an eVar. Then use that to match back to the extension versions that are used in that library.

Hello,

I am the developer of our own extension. I am not asking about how to access the version from other extensions, I showed the code itself of the extension and the extension JSON file. 

I am asking how do I get that version number from the extension JSON file to be available to read in our extension?

Thanks

Oh ok, getting the version number from within your own extension.

Unfortunately, I haven't been able to find a way to do so either. (I too am a developer of a few public extensions, like YouTube Playback and Web Vitals.) I normally have my own constant variable in my code to store my version number. Of course, that means I have to remember to update the version number in various places every time.

If you do find a way to use the version number in extension.json, please share the solution here!
